I'll maybe do a larger setup with CO2 or anything on another project later on, for this on, I'll stay with 2W max. I saw people doing amazing engraving stuff with 200mW diodes, I just expect to be faster. Still in search of opinions to choose between 2W 445nm and 900mW 405nm. Thanks anyway for...

Hi marcuspeh, thank you too. That was a bit the point of the question. How can you tell they will burn equally well ? Does the benefits of the shorter wavelength overcompensate superior mean power (factor 2 here) ?

Thank you again for your answer. For me it's fine because I'm not going to use 635nm red laser on this application. When I talked about reflection, I meant the dot of the laser, impact point of the beam, reflecting on any surface (not mirror) like the wood I'm engraving for example. For this...

Hi Laser Chick, thank you very much for your answer ! :) For the cutting, I'm don't really know, I just feel like it would be good to have the ability to cut, then if I need to later, I can. If I can cut thin plastic, cardboard or plywood, it can be cool. But since the laser will be mounted on...

Hello everybody, :yh: I’m currently in study phase for building a laser module for engraving and cutting on a CNC machine, and I have some questions about it. First of all, I would like to say that I am a newbie in lasers (ignorant but not stupid :p ), but I read quite a lot about it in the...
